Hi all, just registered. Just bought a thunder .40 uc pro yesterday. Seller claimed it was "new in the box". It did come with box and everything in there, but I did notice that it has been fired. Kinda dirty. Just wondering if anyone has or could take a picture of the rifling of their barrel for me. The lands and grooves in this one are VERY shallow, almost non existent. I cleaned the barrel and the do show up a little better, but I'm just wondering if this barrel is worn out or if it's supposed to be this way.
